Assembly:  System.Windows.Forms (in System.Windows.Forms.dll)

Public Event ListChanged As ListChangedEventHandler

The ListChanged event occurs when there is a change to the membership or metadata of the underlying list represented by the List property. For example, this event is raised when items are added, removed, or moved, or the DataSource or DataMember properties change. The values of the Sort and Filter properties will persist when this event occurs.

This event can be completely suppressed by setting the RaiseListChangedEvents property to false. For more information about handling events, see Handling and Raising Events.

The following code example demonstrates handling the ListChanged event of the BindingSource component to detect when the BindingSource component's underlying list is changed.

' This event handler detects changes in the BindingSource 
' list or changes to items within the list.
Private Sub customersBindingSource_ListChanged(ByVal sender As Object, _
    ByVal e As ListChangedEventArgs) Handles customersBindingSource.ListChanged

    status.Text = e.ListChangedType.ToString()
End Sub
